Win back lapsed Booksy clients with a Message Blast

1. Open the Clients tab, tap the filter icon in the top left, choose a group such as Slipping Away and tap Apply.
2. Open client cards from the filtered list to see the last visit and whether a new appointment is already booked, so a regular who just rebooked does not get the offer.
3. Go to More > Marketing > Message Blast and pick email, SMS or a push notification to the Booksy Client App.
4. Choose a template or write your own text, select the recipients and send.
5. Do it again next month. Booksy does not publish how many days without a visit put a client in Slipping Away, and nothing reports back which recipients rebooked after the blast.

Find Booksy clients who have not been in for 45 days and have nothing booked, and send them an email about our Thursday Happy Hour. Show me the list and the text first.

1. 01

   Pick a cutoff that fits the service

   The agent asks list_clients for clients whose last visit is older than the number of days you chose, for example 45 for cuts. You can give different cutoffs, and the agent runs one pass per group.

2. 02

   Drop anyone already booked

   list_appointments for the next 60 days shows who already has a visit coming. Those clients are removed from the list, because a win-back offer to someone booked for Friday reads like a mistake.

3. 03

   Respect the channel and the budget

   Clients without an email are left out of an email blast. For SMS the agent counts recipients against the 2,000 marketing texts in your plan and suggests push or email for Booksy app users when the month is nearly used up.

4. 04

   Show the list and text, then send once

   You see the recipient count, a sample of names and the exact message. send_message_blast runs only after your OK, as a single blast, and the agent logs the date so next week's run skips the same people.

5. 05

   Check who came back

   On the next run the agent compares the previous recipients with new appointments and reports how many rebooked, so you can judge the offer without opening Booksy.

• Booksy sends Message Blast SMS from an automated number, so client replies to the text never reach you.
• Booksy adds a link to your Booksy profile at the bottom of every Message Blast automatically.
• Booksy includes unlimited emails and up to 2,000 marketing SMS a month in the subscription; appointment confirmations and reminders do not count against that limit.
• Booksy automatic campaigns send at most four unique messages a month, so clients in several groups do not get duplicates.

send_message_blast asks for your OK by default. To run it weekly without you, switch confirmation off for that tool in your dashboard.
